This beautiful blue-on-blue specimen is the only such piece I have seen. It features a 2.7-cm "rose" of deepest blue azurite (but blue, not black!), perched atop a matrix coated with various copper minerals (presumably chrysocolla and more azurite). To the right, is a "velvet" drapery of brilliant light blue plancheite (pers comm. analytical result), on which sets a sharp 1 cm azurite crystal. The piece hasn't been cleaned harshly, which might remove some of the swrling colors of the chrysocolla coating. However, if you wished to, the whiteish material could probably be blown off with a water gun. This is a dramatic specimen, and quite unusual for Mexico and seemingly for this find.
